    摘要： A temperature measuring device of a power semiconductor apparatus that accurately detects chip temperature even where a gradient of the measured characteristic line segment is different from a designed gradient, including a chip temperature detecting circuit that includes an A/D converter delivering a measurement value of a digital converted forward voltage across a temperature detecting diode and an operational processing unit for calibration and chip temperature calculation. In calibration processing, different known reference voltages are applied by a reference connected in place of the diode and a gradient of the line segment connecting the measurement values is calculated. The gradient is stored in a memory with an offset correction value that is one of the measurement values. A chip temperature is calculated based on a forward voltage across the diode calculated based on the measurement value and the stored values of the gradient and the offset correction value.

    摘要： The present invention provides a wire saw which cuts a workpiece using a cutting wire and is capable of adjusting wire tension with high responsiveness. The wire saw includes first and second workpiece cutting units 1A and 1B. Each of the workpiece cutting units 1A and 1B includes a pair of guide rollers 10a and 10b around which a wire W is wound to form a workpiece-cutting wire group. The wire saw further includes a tension detector 18 which detects tension in the wire W between the workpiece cutting units 1A and 1B, and a control device 50. The control device 50 changes a rotational speed of the guide rollers 10a and 10b of at least one of the workpiece cutting units based on the tension detected by the tension detector 18 so as to keep the tension within an acceptable range.

    摘要： Power electronics equipment includes a switching device directing current flow to a load and interrupting the current flowing to the load, a control circuit generating a control signal directing the conduction and non-conduction of the switching device, a driver circuit driving a control terminal of the switching device based on the control signal, and at least one air-cored insulating transformer insulating the control circuit and the driver circuit from each other. Each air-cored insulating transformer includes a primary winding and a secondary winding configured to generate a voltage by a change of interlinkage of a magnetic field. The secondary winding includes a plurality of coils configured such that voltages generated by external magnetic flux intersecting the secondary winding are canceled and a voltage generated by the signal magnetic flux intersecting the secondary winding is increased.
